GATE.

Application filed May 18, 1925. Serial No. 31,038.

The present invention relates to a gate and aims to provide a structurewherein the gate is slidable and rotatable on a post, and means areprovided whereby the gate may be lifted and when released willautomatically turn about the post a predetermined distance.

An important object of the invention is to provide a gate structure ofthis nature which is easy to operate, and one which is not liable toeasily become out of order.

The structure of the invention is exceedingly simple and provesthoroughly reliable and efficient in its operation.

With the above and numerous other objects in view as will appear as thedescription proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangement of parts as will behereinafter more fully described and claimed.

In the drawing Figure 1 is an elevation of the gate embodying thefeatures of my invention.

Figure 2 is a fragmentary vertical longitudinal section through the postand a portion of the gate structure, and

Figure 3 is a horizontal detail section taken on the line 33 of Figure 2looking downwardly.

Referring to the drawing in detail, it will be seen that 5 designates avertically disposed tubular gate post which is provided adjacent itsupper end with a pair of longitudinally extending slots 6 which arediametrically opposecl to each other. A second pair of slots 7 areprovided in the post below the slots 6 and are extended diagonally inopposite directions and are diametrically opposed to each other. Asleeve 8 is mounted on the upper portion of the post 5 and a sleeve 9 ismounted on the lower portion thereof. A rectangularly shaped gate frame10 is mounted on these sleeves 8 and 9. The sleeves 8 and 9 are bracedin relation to each other by rods 11 and rods 12 extend from the sleeve8 to the lower corners of the frame 10.

The sleeve 8 is formed with an internal annular groove 13 which receivesthe ends of a pin 14 extending through the slots 6. A link 15 isattached to the pin 14. and extends upwardly through the tubular post 5.A pair of chains 16 are fixed to the upper terminals of the link 15. Acollar 17 is attached to the upper extremity of the post 5 and supportsupwardly and outwardly disposed brackets 18 to the upper ends of whichare pivoted levers 19 having suitable depending handles 20 on the outerextremities thereof. The inner extremities of the levers are attached tothe chains 16. By pulling down upon the handles 20 it will be seen thatthe gate frame and the sleeves 8 and 9 may be raised. a

A pin 22 extends through the slots 7 and is normally held in a positionat the upper ends thereof by means of a spring 23.

A plurality of cam fingers 24 depend from the sleeve 8 about the post 5forming notches therebetween for receiving the extremities of the pin 22and the weight of the gate structure will compress the spring 23 so thatthe pin 22 is in the lower extremities of the slots 7. The fingers 24are provided with cam edges 26 on like sides thereof.

In the present embodiment of the invention there are four of the camfingers 24 spaced at regular intervals about the post 5. When the gateis lifted so that the pin 14 is in the upper extremities of the slot 6as previously described, the weight of the gate will be off of the pin'22 so that the spring 23 will lift the same upwardly and shift theposition of this pin so that when the gate is lowered, two of the camsurfaces 26 will engage with the pin 22. As the gate further lowers, thepin 22 will be moved to the lower extremities of the slots 7, and thenstop so that the continued lowering of the gate with the cam surfaces oredges 26 sliding along the pin 22 will cause the gate to rotate aquarter turn.

The construction, operation, and advantages of the gate will now beapparent without a more detailed description thereof. I have disclosedthe present embodiment of the invention merely by way of example and thesame attains all of the features of advantage enumerated in thestatement of the invention and the above description. It is apparentthat numerous changes in the details of construction, in the combinationand arrangement of parts may be resorted to without departing from thespirit or scope of the invention as hereinafter claimed or sacrificingany of its advantages.

Having thus described the invention, what I claim as new is A gatestructure, including, in combination, a tubular fence post provided witha pair of diagonal oppositely disposed cam slots diametrically opposedto each other, a pin extending through the post and piercing the slots,a spring mounted in the post and associated With the pin for normallyholding it at the upper extremities of the cam slots, a gate including asleeve slidable and r0tatable on the post and having cam fingersengageable With the outer extremities of the pin, and means for raisingthe gate so that the pin may be raised by the spring and shifted to aposition so as to engage other cam fingers as the gate is allowed tolower, so that said fingers cooperate With said pin for automaticallyturning the gate, said means for raising the gate including a pinPI'OJQClJlDg through a pair of vertical slots provided in the post andterminating Within 1 and engaged with said links so that they may 20 beswung for raising the gate.

In testimony whereof I affix my signature.
